Don’t care.
I used Shopping simply because it was a place to find stuff for sale that wasn’t being advertised.
Now I won’t use it anymore, or at least much less often.
It always was being advertised. Merchants feed those products into Google's system. The problems was that because they didn't charge the merchant to do it,there was no barrier against merchants throwing tons of stuff into the system that they didn't have just to get site traffic. By making the merchants pay to list, Google cleared out a lot of spammy or error prone listings.
